TLC5954 LED Driver

We’re switching from the AS1113 to the TLC5954 for driving the 128 LEDs of our bargraphs, because 48 channels are better than 16. This will divide by 3 the number of chips that we need to mount on every bargraph, bringing it from 24 down to 8. Also, the TLC5954 provides a standard SPI interface, which will make integration with the ATmega328 microcontroller a lot easier.
